Pinpoint Triggers
B Trigger After Delay Time
The A trigger arms the instrument.
Posttrigger acquisition starts on the first B
edge after the trigger delay time.
Triggering with Reset
You can specify a condition to reset the
trigger system if it occurs before the B trigger
event. When the reset event occurs, the
trigger system stops waiting for the B event
and returns to waiting for the A event.
Triggering with reset is not available on
MSO5000 and DPO5000 instruments.
Quick Tips
B-trigger delay time and horizontal delay time are independent functions. When you establish a trigger condition using
either the A trigger alone or the A and B triggers together, you can also use horizontal delay to delay the acquisition
by an additional amount.
Correcting Trigger Position
Trigger position correction corrects for differences in the data path and the trigger path to more accurately place the trigger
on the displayed waveform. Trigger position correction can also use averaging to more accurately place the trigger on noisy
signals. To more accurately place edge triggers on the display, perform the following procedure.
